PEG/PPG-18/4 COPOLYMER

Description

PEG/PPG-18/4 Copolymer is a synthetic ingredient widely used in skincare and personal care products. This water-soluble polymer is a combination of polyethylene glycol (PEG) and polypropylene glycol (PPG) units, with an average of 18 ethylene oxide units and 4 propylene oxide units per molecule. Its primary function is as an emulsion stabilizer and viscosity control agent.

In skincare formulations, PEG/PPG-18/4 Copolymer helps create stable emulsions by reducing the surface tension between oil and water phases. This property enables the creation of smooth, uniform products with improved texture and consistency. The ingredient also contributes to the overall feel of the product, enhancing its spreadability and leaving a non-greasy finish on the skin.

Additionally, PEG/PPG-18/4 Copolymer acts as a mild surfactant, aiding in the cleansing process without causing excessive dryness. It can also function as a solubilizer, helping to incorporate oil-soluble ingredients into water-based formulations. The polymer's ability to form a thin, flexible film on the skin surface can provide a temporary moisturizing effect and help protect against environmental stressors.
